A flexible battery (10) has at least one cell group (12) comprising four unit cells (13) of the solid-electrolyte type formed on a flexible substrate (11). The cell group (12) has a rectangular shape, and is divided into the four unit cells by strip-shaped portions (14a,14b) which are arranged along two diagonal lines of the rectangle and reduce the possibility of the battery being damaged by bending or twisting. |
